Re: Reloading for 30-378 wby
98 gr of H-1000 over a Fed 215 M primer and under a 210 Berger Hunting VLD seated at mag box length which will be about 3.800" Expect 3050 fps, from a 26", 3120 from a 30" great accuracy and great killing potential to way out there.
This is my old tried and true load for the 30-378 load I hunted with for a few years with great success. It is very easy on that expensive and very soft Weatherby brass too.
But today we have the option of the 215 Berger Hybrid which could be substituted for the 210. And also the 230 which you should drop about 6 gr on the charge and work back up watching for pressure.
